A New method of keeping garlic fresh
The basal leaves of garlic were sprayed with 0.2% chlorophyllin MH bud inhibitor 10 days before harvest. MH bud inhibitor is absorbed by leaves and transferred to the buds of garlic cloves so as to inhibit its growth and achieve the purpose of fresh-keeping. With this method, the garlic can be stored until April of the following year.
Spraying should pay attention to the following points:
1. Do not water the liquid 3-4 days before spraying. If it rains within 24 hours after spraying, replenish the liquid immediately according to the original dose after sunny day.
Second, strictly control the concentration of chloranthin MH bud inhibitor, not more than 0.2%. The best time to spray the liquid is one week before harvest.
Third, because there is a waxy layer on the garlic leaves, the liquid is easy to slip, so a small amount of soap or washing powder can be added to the solution to increase the adsorption of the liquid. The treated garlic still needs to be stored in a ventilated and dry environment.

The function of essential nutrient elements in garlic and its corresponding deficiency symptoms
Garlic likes loose soil rich in humus, has strong adaptability to soil acid and alkali, and grows well under slightly alkaline conditions. In different growth stages of garlic, nitrogen requirement was the highest, followed by potassium, calcium, phosphorus and magnesium. For every 1000 kg of fresh garlic, it is necessary to absorb 4.5 kg of nitrogen, 1.3 kg of phosphorus and 4.1 kg of potassium, and the proportion is about 0.25Mel 0.9. The root system of garlic is string fleshy root system, which is mainly distributed in the plough layer of 5-25cm and belongs to shallow root vegetables.
